|
|
| I wanted to start a thread about people's configuration to maximize bandwidth. I have heard about some facilities "hacking" the software to open up the ceiling so to speak, but have not confirmed that info. Does anyone out there see better than 800mb/s on their SAN? is Xsan2 able to address this. I'd love to hear how people have built their "Ferraris" of san installs. |

Do you mean 800+ on one client?
I've seen 650ish on a dual 4Gb client.

I believe that 500MB per sec is the theoretical 4Gb limit so we'd be looking at 250MB for 2Gb.
That said, that's theoretical, like Communism.
If you want sheer numbers, hook up a bunch of raids volume-based, with a 4 port atto. Take speedy RAID-5's and "0" them together and I'll bet you could flood the bus. But... You'll still bump up against the finder limits. |

So what are people actually seeing with a single Promise raid on 4Gbit fiber configured with the apple 1MD and 2 DATA LUNs configuration?
With AJA speed system test for instance? What are the read/write you manage to get out of that config? |

I'm seeing about 70MB/sec write, and 145MB/sec read via 2G FC, dual channel.
Since that isn't maxing out 2G, I would tend to think there is some bottleneck.
I haven't tried just a direct connect 1 LUN Raid5. |
